Complementary and alternative therapy use in gynecologic oncology: implications for clinical practice

Barriers to Acupuncture Use Among Breast Cancer Survivors: A Cross-Sectional Analysis

Introduction: Increasing evidence suggests that acupuncture may be helpful to manage common symptoms and treatment side effects among breast cancer (BC) survivors. Acupuncture usage among BC survivors remains low with little known about the barriers to its utilization. We evaluated perceived barriers to acupuncture use among BC survivors and explored the sociodemographic variations of such barriers. Methods: We conducted a cross-sectional analysis at an urban academic cancer center on 593 postmenopausal women with a history of stage I-III hormone receptor-positive BC who were taking or had taken an aromatase inhibitor. We used the modified Attitudes and Beliefs about Complementary and Alternative Medicine instrument to evaluate patients’ perceived barriers to acupuncture. Multiple linear regression analysis was performed to determine sociodemographic factors associated with perceived barrier scores. Results: The most common barriers were lack of knowledge about acupuncture (41.6%), concern for lack of insurance coverage (25.0%), cost (22.3%), and difficulty finding qualified acupuncturists (18.6%). Compared with whites, minority patients had higher perceived barriers to use acupuncture (β coefficient = 1.63, 95% confidence interval = 0.3-2.9, P = .013). Patients with lower education had higher barriers to use acupuncture (β coefficient = 4.23, 95% confidence interval = 3.0-5.4, P < .001) compared with patients with college education or above. Conclusion: Lack of knowledge and concerns for insurance coverage and cost are the common barriers to acupuncture use among BC survivors, especially among minority patients with lower education. Addressing these barriers may lead to more equitable access to acupuncture treatment for BC survivors from diverse backgrounds.

Metabolism, Biochemical Actions, and Chemical Synthesis of Anticancer Nucleosides, Nucleotides, and Base Analogs

Nucleoside, nucleotide, and base analogs have been in the clinic for decades to treat both viral pathogens and neoplasms. More than 20% of patients on anticancer chemotherapy have been treated with one or more of these analogs. This review focuses on the chemical synthesis and biology of anticancer nucleoside, nucleotide, and base analogs that are FDA-approved and in clinical development since 2000. We highlight the cellular biology and clinical biology of analogs, drug resistance mechanisms, and compound specificity towards different cancer types. Furthermore, we explore analog syntheses as well as improved and scale-up syntheses. We conclude with a discussion on what might lie ahead for medicinal chemists, biologists, and physicians as they try to improve analog efficacy through prodrug strategies and drug combinations.

Knockdown of hTERT by siRNA inhibits cervical cancer cell growth in vitro and in vivo

Human telomerase reverse transcriptase (hTERT) is the catalytic component of telomerase that facilitates tumor cell invasion and proliferation. It has been reported that telomerase and hTERT are significantly upregulated in majority of cancers including cervical cancer, thus, downregulation of hTERT is a promising target in malignant tumor treatment. We established a short interfering RNA (siRNA) targeting hTERT, and transfected it into HeLa cells (a cervical cancer cell line) to investi-gate the effect of cell proliferation, apoptosis, migration and invasion in cervical cancer cells. The results showed that siRNA targeting hTERT could effectively knock down hTERT expression, remarkably suppress telomerase activity, cell proliferation, migration and invasion, and induced cell apoptosis of cervical cancers cells in vitro. In addition, we evaluated whether siRNA targeting hTERT affects tumor growth in nude mice, and found that it dramatically inhibited tumorigenesis and growth of mice injected with siRNA targeting hTERT. Furthermore, we also found that knockdown of hTERT was able to significantly suppress constitutive phosphorylation of Akt, PI3K, which might imply that reduction of hTERT inhibited tumor growth via the PI3K/Akt signaling pathway to some extent. These results suggest that the suppression of hTERT expression by siRNA inhibits cervical cancer cell growth in vitro and in vivo, and may provide a novel target for anticancer gene therapy.

The value of acupuncture in cancer care

Clinical research on acupuncture in cancer care is a new and challenging field in oncology. The results of clinical research will continue to provide clinically relevant answers for patients and oncologists. The evidence currently available has suggested that acupuncture is a safe and effective therapy to manage cancer and treatment related symptoms, while giving patients the ability to actively participate in their own care plan. The article explains the potential benefits of acupuncture and describes the difficulties in studying its effectiveness.

Self-application of complementary and alternative medicine by patients with gynecologic cancer

OBJECTIVES

In this study we aimed to determine the epidemiology and demographic data on complementary and alternative medicine (CAM) use along with the medical/surgical treatment modalities in patients with gynecologic cancers in Turkey.

MATERIALS AND METHODS

A cross-sectional study was designed to determine demographic data on CAM use of patients with gynecologic cancers who had medical and/or surgical treatments. Semistructured questionnaires were used for collecting data from 126 patients.

RESULTS

When the CAM use ratio of patients was evaluated with respect to demographic characteristics, patients using any type of CAM were younger and more educated, and there were no significant differences between the patients who used and who did not use any type of CAM with respect to geographical region. There were no significant correlations between the use of CAM and the type of malignancy, treatment modality and time period after diagnosis.

CONCLUSION

There is critical concern about the probable serious risks associated with non-educated CAM practitioners. Therefore, informed and educated healthcare professionals should inform and help in relieving patients in a more professional and multidisciplinary way.

Acupuncture for side effects of chemoradiation therapy in cancer patients

OBJECTIVE

To review strategies and recommendations to improve utilization of acupuncture treatment for side effects of chemoradiation therapy in cancer centers.

DATA SOURCES

Research studies and articles, government reports, and author experience.

CONCLUSION

Recent evidence in clinical research indicates that acupuncture is beneficial for chemotherapy-induced nausea, vomiting, and cancer pain. Other preliminary data also suggests acupuncture might be effective for chemotherapy-induced leukopenia, postchemotherapy fatigue, radiation therapy-induced xerostomia, insomnia, and anxiety. However, the utilization rate of acupuncture remains low despite the wide use of other complementary and alternative medical therapies among cancer patients. This low usage of acupuncture in cancer patients indicates a health care quality issue.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses need to increase their awareness of the available evidence in the use of acupuncture in the supportive care of cancer patients.
